Kobkul place was great, she is a super nice lady. The only thing is that the internet doesn't really work in the room.
But work downstair.
For breakfast, she made me a delicious latte and gave me some fruit and pastries from
the Chinese New Year... the Pad Thai restaurant across the street is one of the best in the city, it was delicious and inexpensive.
I highly recommend Kobkul place, it is very easy to go anywhere in Bangkok from her location, and she is a really helpful and caring host.
